GENERAL PURPOSE TUBES

The general purpose tubes and hoses are used for the general purposes which do not require high range of purity of the compound. These are mostly used in many domestic appliances and in the workshops or hobby applications because of their excellent flexibility.

MEDICAL/FOOD GRADE TUBES

These are specially designed hoses and tubes which are made in a manner so that they do not react with any medical or food material. They are sterilized in standard autoclaves in order to make them fit for the application in which they come in close contact with the food ingredients, body tissues and fluids or sensitive drugs. In this particular type of tubing the manufactured silicone tubes and hoses are completely tasteless, odorless, and non-toxic with a special property which does not support bacterial growth.

The high pressure tubes and hoses are made by strengthening their composition with wire or polyester braids which combats expansion and flattening. These tubes are mostly used when then the tubes are in direct contact with pressurized gases or suction is conducted. However, sharp edged clamps and fitting should be avoided near the tubes as they have low tensile strength and resistance to steam which may cause excessive wear and tear.

USES OF SILICONE TUBES IN THE INDUSTRIAL SECTOR

Silicone has a multiple usage in the industrial sector because of its excellent properties and types which provide a very wide area for functioning. Some of these uses are:

Protection Rubber Bellows, Synthetic Rubber Bellows, Mumbai, India

Protection Rubber Sheets

protection rubber bellow is a form of expansion joint which is made flexible in order to endure heat and various other pressures from a synthetic elastomer. The elastomer is moulded into a spherical shape with metal floating flanges for better adjustment. The moulded shape of the bellow is ideal for compensation for misalignment along with neutralizing the movement, reducing the noise and vibrations inside the pipelines. They work efficiently in dampening the sound and vibrations and can be used under a wide range of circumstances and conditions such as under water or in contact with oils, chemicals, gases or in the food industry.

The flexible rubber bellows are designed to take load and pressure from all directions:

Axially along the movement of elongation and compression.
Laterally when there is offset movement.
Angularly when the movement is around the bend.

TYPES OF PROTECTION RUBBER BELLOW

There are a variety of manufactured bellows during various industrial purposes. Some of them are:

TYPES OF RUBBER USED FOR THE MANUFACTURE OF PROTECTION RUBBER BELLOW

The rubber bellows are primarily made from using seven distinct types of synthetic rubbers which are:

APPLICATIONS OF THE VARIOUS TYPES OF SYNTHETIC RUBBER BELLOWS

MATERIAL	COLOR	APPLICATION
EPDM	Red	Heating and ventilation systems, hot water exposure, weak acids and alkalis
EPDM	Double Red	Extremely high temperature water exposure, heating and ventilation systems, weak acids and alkalis
NITRILE	Yellow	Oil and gas transportation, refineries
HYPALON	Green	Chemical industry for use with acids and water
VITON	Purple	High temperature applications, transportation of petrochemicals/ chemicals/ oils/ solvents
FOOD GRADE NITRILE	White	Food stuff transportation, water distribution
BUTYL	Blue	High temperature applications

INSTALLATION OF PROTECTION RUBBER BELLOW

The installation of the protection rubber bellow is fairly simple and can be done using the following steps:
For the process of installation the elbow should be compressed and stretched slightly to remove any form of misalignments
If the rubber has to be stretched during installation it is advisable that the collar of the sealing ring is kept in position.
Load the necessary compression required for installation between the flanges.
Install the bellow in such a manner that the manufacturing date is clearly visible on top for further references.
Try to insert the bolts from rubber bellow side. However, in case of difficulty loose threaded end must be kept out of interference zone for

maximum benefits and movement of the bellow.

PRECAUTIONS BEFORE AND AFTER THE INSTALLATION OF THE PROTECTION RUBBER BELLOW

The bellow is made of rubber and some precautions are necessary to avoid early wear and tear during the installation procedure. Some key points that might need the consideration of the engineer installing it are:
Avoid using sharp tools as it might damage the rubber of the bellow.
Installation of the bolts should be performed crosswise.
Apply extra force to tighten the bolts by hand.
Fasten each bolt until it is secure and immovable.
